Air quality test method for living rooms and working rooms as well as external air

摘要

The method for testing is carried out by a passive application of an absorbent the material on it is enriched. Subsequently it is filled in a ceramic tube and using microwave energy is thermally desorbed, and determined gas chromatographically. An amount of between 25-200 mg of the absorbent used for the enrichment is exposed in a dish, open between one and twenty-one days. The absorbent is exposed in a reverse clamped cell, with the opening downwards, and suitably fixed between two layers of filter paper.
